The relay should be under the hood located inside the small black box that is about 6 or8 inches square. should be a diagram inside the cover showing which is for the fuel pump relay. If you have someone else turn the key, you should be able to hear or feel it click for just a coulpe of seconds when the key is turned on. Straps on tank have a bolt that holds one end and they are held on by a T-slot on the other end.

I have a 2003 yukon Problem with the GMC Yukon XL


What size engine ? 4.3 L vortex P0300 random misfire code is usually associated with vacuum leaks , but could also be low fuel pressure , plugged fuel filter , fuel pump problem , clogged injectors etc... doing fuel pressure an flow testing would confirm or eliminate that as a problem . Fuel injector balance testing would confirm or eliminate clogged injectors .

I have 2003 ford expedition,when engine is cold my expedition is hard to started... what should i do..


Sounds like you have a fuel pressure issue. These trucks are bad about bleeding all the fuel pressure off when the engine is shut of but will run fine when started. the only good way to check this is to install a fuel pressure gauge on the shrader valve on the fuel rail. Once you get it isntalled start the engine and let it run for a minute or so,shut the engine off and it should hold pressure,if it bleeds off quickly it means the check valve on the pump is leaking and it will need a fuel pump.

Need help with my 99 gmc yukon! replaced map sensor, and idle air control module. getting gas to shaffer valve, getting spark to the spark plugs. yellow fire.


Im guessing the vehicle wont start? If so you shouldnt rule out fuel just because your getting fuel to the shrader valve, these vehicle require a certain amount of fuel pressure to run, im guessing around 60psi, so i would check fuel pressure, if ok keep in mind that these vehicles also had a problem with early failure on the fuel injectors, GM sells a new design injector set up for them.

2002 yukon xl no power check engine light


FROM: LustyKid

Denalis are famous for clogged fuel filters. Change the fuel filter first and see what happens, Get the code for the check engine light. It could be you have a clogged EGR ports. Remove EGR valve and clean out the ports, replace with new gasket and see what happens. Advise of results.
